+Apparently we're not currently doing anything special with busybox,
+just using the default nixos build with the default applets.
+
+We'd like to be able to say in modules which applets they need,
+so that we build all necessary applets but don't waste any space.
+But we don't want to build a busybox for each module because that
+would be a big waste of space.
+
+One option:
+- add busybox configuration to `config` so that modules can maul it
+- add a busybox module that builds it with union of all config and
+ adds link in /bin
+- make everything else look in /bin instead of referencing pkgs.busybox
+
+It would be good if services could assert somehow that their required
+config is present

+We have ath9k listening for packets. To make this ready to use:
+
+- need to load the modules
+- enable bridging lan with wlan
+- packet forwarding
+- firewall

+
+The wlan test is failing because we moved mac80211 to a module and
+there's nothing running to insmod it

+bridge is e2b3738d0f8c3f2fd76ebcef65612de502a7b121 but it's the wrong
+way around: the master interface needs to be up whether or not all
+of its children are, so members depend on master not vice versa
+
+Next steps:
+- re-implement bridge, enable bridging lan with wlan
+- packet forwarding
+- firewall
+- ath10k
+- ipv6

+
+bridging wlan was made complex because can't add a device to a bridge
+until it's operational, and wlan0 is not operational until hostapd
+has churned awhile. Therefore, "waitup" listens for netlink messages
+and notifies s6 readiness stuff
+
+we have a firewall nft script but we're not running it on boot
+
+we have forwarding but no dns, maybe because we haven't told
+dnsmasq about any upstream servers
